  1. Re:article is an oversimplification on Army of Davids Beats Pentagon Procurement · · Score: 1

    IAANAT (I Am A Navy Acquisition Type). Don't give me the "ditching the peacetime acquisition system would fix this" argument - innumerable, half-assed products are developed and dumped on the troops during wartime in the name of getting things to the field quickly.

    Hell - that even happens during peacetime.
     
    True story:
     
    In the mid 80's the Navy finally exhausted the stock of a special switch used in the Posiedon and Trident Backfit weapons systems, the original stock having been purchased back in the 1960's. The couldn't, for some convoluted reason, get a replacement made to the same specification - it was about a half inch longer. (IIRC it had something to do with the connector plug - which would have had to have special production run as it too was no longer available.)
     
    Now, when installed this switch projected into a plastic 'wart' glued to the side of a larger plastic cover. The Navy reasoned, logically enough, that it would be simple to proactively replace this 'wart' with one large enough to house the new switch. So they made up kits with the new 'wart' and some glue to hold them on and shipped the kits to the Fleet.
     
    Where the new 'warts' promptly fell off within a day or two of installation.
     
    Turned out - the contractor *and* the Navy QA folks had tested the fix at the training centers, which were not made of the same plastic as the ones in the fleet! There had been two production runs of the covers - but all the ones at the training centers were from the second, while almost all the ones in the Fleet were from the first. There were two runs because the training centers had exhausted the original stock - the covers their were removed and replaced on a weekly basis during maintenace training, while the covers in the Fleet stayed in place unless something actually broke, which it rarely did.

Bound as a reasonable solid of some form, how much volume are we talking? I'm rejecting liquid CO2 or dry ice out of hand due to the energy requirements of storing it. No can you strip the O2 off of it - pure carbon is flammable as hell.
     
     

    Ideally, you'd run the process on solar energy I suppose. Hmm... an air scrubber that runs on solar energy. Sounds suspiciously like a tree!

    If only it were that simple - elsewhere someone has calculated that it would require an area twice the size of Texas to hold enough trees. I can't think of an area that large that a) will support trees without massive intervention and, b) it won't constitute a massive ecological disaster in it's own right to rip out what is there and replace it with trees. Even if such an area existed - it's still not simple, you need to design your farm carefully (avoiding monoculture and having tall trees shade smaller ones), and protect it from pests, disease, and fire.
     
    Now, a solution that will occur to any slashdotter worth his salt is to go distributed - plant 'em all over the place. Now you run into the problem of tracking 2.25 * 10^11 trees scattered over the face of the earth. A daunting prospect to say the least.

  11. Re:I RTFA on The Death Of CS In Education? · · Score: 1

    The problem is a much deeper-lying one. Universities are selling themselves as steps towards getting jobs. With very rare exceptions (divinity, for instance) this was never the case, nor was it intended to be. They are not vocational institutions, nor are they designed as such.

    Actually - historically, vocational training was exactly what colleges and universities were designed for. The trivium and quadrivium were designed to produce trained and cultured minds suitable to the clergy, the law, and to be administrators. Sons of the nobility attended because, when they weren't filling those roles directly, they would be supervising those fields. Education was designed to prepare one for ones role in society. (This is why 'going to college' was the goal of so many youths in the 19th and early 20th centuries - because being a college graduate marked one as being of a higher station in life.)
     
    The idea of a university or college being a home for scientific exploration came rather later. The idea of one being merely to 'expand minds' is a fairly modern invention, or more correctly a modern ideal as it fails to correspond to any institution past or present.
     
     

    Universities are not about drilling students. They are set up to expand minds. In principle a university could be a few comfortable seating areas around a vast library, with students exploring under the guidance of other people interested in expanding human knowledge. Add a few laboratories, maybe a few lecture halls for guest presentations, and you're there.

    A fanciful ideal - one thats been around for less than a century. Somehow, nobody has been able to make one work. Or even, as far as I know, tried to make one work. That suggests a large disconnect between the ideal and the nitty-gritty of reality.
     
     

    The writer of the article wants student numbers up, and shows little or no interest in the raison d'etre of the courses and departments in the first place. His agenda, as revealed by the article, is for universities to be, or to become, vocational institutions.

    A study of history shows his agenda is for universities to refine their approach to something that they have historically done. Your belief that it represents a radical agenda for change is based on an erroneous belief of the roles of the university in the past.

This means he could have put off on any decision on whether to accept the prize until the very last minute. At least as far as the tax man is concerned.

    My wife, a CPA by profession, says different. The ticket has a cash value- accepting the ticket is tantamount to accepting the cash, even if he never takes the flight. The article suggests that you make the argument that it has no cash value until redeemed - but the IRS may or may not accept that argument.
     
     

    The only craft that matches the specs of those announced in the contest press release are those of the Virgin Galactic SpaceShip 2. And since Virgin Galactic's commercial craft is a minimum of 2 years from sending customers into space, he had at least that much time to defer his decision. His financial situation could be much improved by then. Since space craft are rarely delivered on schedule, he would likely have had even more time to defer his decision.

    That's called deferring income. Businesses can do it under certain circumstances - but it's very, very dodgy for an individual to try.
     
     

    Then there's the possibility that he could have worked his way out of paying much of any tax at all. As others have suggested, if he could have taken some on professional duties in the form of writing about his voyage, he could have partially or wholly written off his tax burden.

    That's another dodgy route - as such expenses are usually only allowed to be written off when the individual is a professional [writer] or engaged in a related [space, travel, or writing] business. A one type expense of that nature, without evidence of an ongoing related pattern of behavior, is highly likely to be disallowed. (If you are lucky. If you are unlucky - a charge for tax fraud or tax evasion could also be yours.)
     
     

    So why did this guy refuse the prize two or more years before it would have had any financial impact on him? Why didn't he look into any professional options for writing off the tax? Good question. My guess is either very bad tax advice or sheer lack of courage.

    My guess is that he got very good tax advice - because I discussed the issue with a tax professional and she disagrees completely with you. She agrees that he could take a chance by choosing to defer or to attempt to create a professional justification - but emphasizes those paths of action are not without significant potential risk.
